"Metacalyptic" broke teh Intertron. Google only came up with Cap'n sites, actually. So I'm forced to do something I loathe: think. Here's what I've got, but I think I need help/tweakage.

Apostasy is an easy one. Metacalyptic I guess to be something like "after covering/hiding," or 'cause it's funnier, the aftereffect of the opposite of an apocalypse. The question then becomes, "Is 'metacalyptic apostasy' that which follows the coverup of a rejection of faith/allegiance?"
